PRESERVING PILES.

SPECIFICATIONforming part of Letters Patent No. 511,372, dated December 26, 1893.

Application tiled October 6, 1891. Serial No. 407.867. t No model.)

in the county of Ventura and State of Cali-V fornia, have invented certain new and useful Improvements in Preserving Piles; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to an improved covering for piles, and consists of the construction and arrangement of the parts hereinafter more fully described and claimed.

In the accompanying drawings Figure 1 is a view in side elevation of a pile provided with my improved covering. Fig. 2 is a horizontal sectional View thereof. Fig. 3 is a similar view of a modification.

In carrying out my invention the bark is first removed from that portion of a pile, A, from a point beneath the part which extends from the bottom of the shifting sand up to and above high water mark. After this portion of the pile is well smoothed tar ct is applied to the pile, several coats thereof being given, each after the last preceding coat is thoroughly dried. v

B is a covering or jacket which is designed to inclose the tarred portion of the pile. This covering consists of a series of battens b of redwood. Before securing this covering in place the inner surface thereof is well treated to several coats of tar. The covering is then attached to the pile by nailing, and a series of wire bands b. After the covering is firmly secured in place the same is well tarred on its outer surface, and the last or final coating of tar is covered with sand while still in a moist state.

By covering piles in the manner stated they will preserve their original strength for a great space of time and are not as liable to suffer by reason of vessels striking against them as are unprotected piles.

It is not absolutely essential to remove the bark from the piles before coating the same with coal tar, but it is preferred to do so. In some instances a covering O (Fig. 3) of burlap can be applied to the outer surface of the pile before tarring the latter. The last two coats of coal tar put on the battens, together with about one-eighth of one inch of beach sand, dry on the battens and after they dry form a cement.

I claim as my invention- In combination with a pile a covering consisting of a coating of tar applied thereto which is placed thereon in series after each preceding coating has dried, a series of battens of redwood over the tar coating having tar applied to the inner surfaces thereof, a series of bands surrounding said battens, an outer coating of tar applied to said battens and over said bands, and a thick coating of beach sand applied to said outer coating of tar While the latter is still moist to form a cement, substantially as described.

In testimony whereof I aihx my signature in presence of two witnesses.

ROBT. SUDDEN.
